Eaton P3BKDC3350 Pow-R-Way III plug-in breaker - 200 kAIC
Part Number: P3BKDC3350
Quick Summary
The Eaton P3BKDC3350 Pow-R-Way III circuit breaker plug-in unit protects busway systems in industrial enclosures. This solution addresses downtime and safety challenges when protection devices don't align with fast-moving busway installations. Certified to ANSI UL 857, IEEE standards, and CSA certification, it also respects NEMA compliance for rugged industrial environments. Reliable protection, scalable 350 A capacity, and straightforward busway integration translate to lower lifecycle costs and faster project delivery. Using a plug-in design minimizes downtime during maintenance and enables quick replacement without rewiring. For project teams, that means predictable lead times, easier spare-part planning, and compliant, auditable protection across multiple fabrication lines.
